Web1 jul. 2024 · Types of Ion Exchange Equipment. Water softeners replace calcium, iron, magnesium and other metallic ions with sodium ions. They treat “hard water” and prevent … Cation-exchange capacity is defined as the amount of positive charge that can be exchanged per mass of soil, usually measured in cmolc/kg. Some texts use the older, equivalent units me/100g or meq/100g. CEC is measured in moles of electric charge, so a cation-exchange capacity of 10 cmolc/kg could hold … Meer weergeven Cation-exchange capacity (CEC) is a measure of how many cations can be retained on soil particle surfaces. Negative charges on the surfaces of soil particles bind positively-charged atoms or molecules … Meer weergeven Cation-exchange capacity is measured by displacing all the bound cations with a concentrated solution of another cation, and then … Meer weergeven Positive charges of soil minerals can retain anions by the same principle as cation exchange. The surfaces of kaolinite, allophane and iron and aluminium oxides often carry positive charges. In most soils the cation-exchange capacity is much greater than … Meer weergeven The amount of negative charge from deprotonation of clay hydroxy groups or organic matter depends on the pH of the surrounding solution. Increasing the pH (i.e. decreasing the concentration of H cations) increases this variable charge, and … Meer weergeven Base saturation expresses the percentage of potential CEC occupied by the cations Ca , Mg , K or Na .

WebExchange capacity is the amount of impurity that a given amount of resin can remove, and it has units of moles/ml, equivalents/ml, or moles/gm. The anion resin is less dense than the cation resin; thus, it has a smaller exchange capacity, and a larger volume is needed for anion resins than for the cation resins to obtain equal total exchange capabilities. WebTotal ion exchange capacity Total amount of chemical equivalents available for exchange per unit weight or unit volume of resin. Ion exchange is a process used to remove …
